For the past several years, researchers at the University of Illinois at Urbana-Champaign have reverse-engineered native biological tissues and organs — creating tiny walking “bio-bots” powered by muscle cells and controlled with electrical and optical pulses.

Now, in an open-access cover paper in Nature Protocols, the researchers are sharing a protocol with engineering details for their current generation of millimeter-scale soft robotic bio-bots*.

Hiroshima University researchers and associates have developed a terahertz* (THz) transmitter capable of transmitting digital data over a single channel at a speed of 105 gigabits per second (Gbps), and demonstrated the technology at the International Solid-State Circuits Conference (ISSCC) 2017 conference last week.

For perspective, that’s more than 100 times faster than the fastest (1 Gbps) internet connection in the U.S. or more than 3,000… read more

York University scientists have created the first in vitro (lab) 3D heart tissue made from three different types of cardiac cells that beat in synchronized harmony. It may lead to better understanding of cardiac health and improved treatments.*

The researchers constructed the heart tissue from three free-beating rat cell types: contractile cardiac muscle cells, connective tissue cells, and vascular cells. No external scaffold was used and the… read more

A new set of machine-learning algorithms developed by researchers at the University of Toronto Scarborough can generate 3D structures of nanoscale protein molecules that could not be achieved in the past. The algorithms may revolutionize the development of new drug therapies for a range of diseases and may even lead to better understand how life works at the atomic level, the researchers say.

Scientists at The Scripps Research Institute (TSRI) have developed the first stable semisynthetic organism — a bacterium with two new synthetic bases (called X and Y) added to the four natural bases (A, T, C, and G) that every living organism possesses. Adding two more letters to expand the genetic alphabet can be used to make novel proteins for new therapeutics, according to the researchers.

Four advanced ALS (amyotrophic lateral sclerosis) patients who were “completely locked in” (totally unable to communicate) for years have suddenly broken through in a lab at the Wyss Center for Bio and Neuroengineering in Geneva, Switzerland — communicating a “yes” or “no” by simply thinking the answers.

The brain–computer interface (BCI) system achieved this remarkable breakthrough by using functional near-infrared spectroscopy (fNIRS) to measure changes in blood… read more

Libratus, an AI developed by Carnegie Mellon University, has defeated four of the world’s best professional poker players in a marathon 120,000 hands of Heads-up, No-Limit Texas Hold’em poker played over 20 days, CMU announced today (Jan. 31) — joining Deep Blue (for chess), Watson, and Alpha Go as major milestones in AI.

Libratus led the pros by a collective $1,766,250 in chips.* The tournament was held… read more

Mayo Clinic researchers have found that engaging in mentally stimulating activities, even after age 70, was associated with decreased risk of new-onset mild cognitive impairment (the intermediate stage between normal cognitive aging and dementia)over an average study period of 4 years.

The study discovered that for cognitively normal people 70 or older, the risk of new-onset mild cognitive impairment decreased by 30 percent with computer use,… read more

An international team of scientists has developed a soft robotic sleeve that can be implanted on the external surface of the heart to restore blood circulation in pigs (and possibly humans in the future) whose hearts have stopped beating.

The device is a silicone-based system with two layers of actuators: one that squeezes circumferentially and one that squeezes diagonally, both designed to mimic the movement of healthy hearts when… read more

In an open-access paper published online January 26, 2017 in the journal Cell, Salk Institute researchers report breakthroughs on multiple fronts in the race to integrate stem cells from one species into the early-stage development of another species (or chimeras**).

Don’t throw away your bifocals or multiple glasses yet, but those days might soon be over. A team led by University of Utah engineers has created “smart glasses” with liquid-based lenses that can automatically adjust the focus on what you’re seeing, at any distance.

They’ve created eyeglass lenses made of glycerin, a thick colorless liquid, enclosed by flexible rubber-like membranes in the front and back. The rear… read more

Geneticists solve a decades-long puzzle about how genes are turned on to make cellular proteins

January 27, 2017

Molecular biologists at the University of California, San Diego (UC San Diego) have discovered a short sequence of DNA that is essential for turning on (expressing proteins) more than half of all human genes — an achievement that should provide scientists with a better understanding of how human genes are regulated.

Knowing what turns on genes is important. Each human cell contains about six feet of DNA, a double-helical molecular… read more

Deep learning has been touted for its potential to enhance the diagnosis of diseases, and now a team of researchers at Stanford has developed a deep-learning algorithm that may make this vision a reality for skin cancer.*

A prototype 3D bioprinter that can create totally functional human skin has been developed by scientists from Universidad Carlos III de Madrid (UC3M) and BioDan Group in Spain. The skin has been used to treat burns as well as traumatic and surgical wounds in a large number of patients in Spain, according to the scientists.
